PHASE 1 - September 1, 1997 to August 31, 1998

Goals and Objectives

Phase 1 Goal:

The goal of the first phase of the cadastral data framework is to develop and test an interorganizational partnership approach to create, manage, and distribute cadastral data for the state of Washington.

Phase 1 Objectives:

A common cadastral data model for the state of Washington will be implemented and will be fully compliant with Federal Geographic Data Committee (FGDC) cadastral data standards.

The cadastral framework will be a feature level database.

Environmental Systems Research Institute (ESRI) Spacial Database Engine (SDE), or a similar product, and Oracle database management software will be utilized for the framework data. This will not be a software requirement for framework partners.

Framework data criteria and specific data requirements will be developed to provide guidelines for cadastral framework data inclusion from partner organizations.

Cadastral data from at least three partner organizations will be accepted and integrated within a test county. The accepted data must meet the framework data criteria and specific data requirements that partner organizations have agreed upon.

Framework data integration will be supported by Washington Department of Natural Resources and at least one designated data expert from each data-providing partner organization.

Washington Department of Natural Resources and data provider organizations in the test county will coordinate with the U. S. Bureau of Land Management and associated contractors to test the development of automation tools for "crosswalking" data to the FGDC cadastral data standards and for data conversion to a standard transfer profile format.

Data maintenance procedures and methods will be researched and evaluated for future phases of the cadastral framework project.

The cadastral framework data and metadata will be made available through the internet NSDI Clearinghouse node in Washington state linked to the Washington Department of Natural Resources World Wide Web server.

Cadastral framework project oversight will come from the Washington Framework Work Group and the Washington Geographic Information Council.


PHASE 1 - September 1, 1997 to August 31, 1998

Project Development Stages and Timelines


Completion Date: February 1998


Completion Date: June 1998


Completion Date: August 1998


PHASE 1 - September 1, 1997 to August 31, 1998

Data Deliverable

Department of Natural Resources (DNR) data to be included:

Legal Area Descriptions

Public Land Survey System (PLSS) grid for state

Other Survey System (used for DNR ownership)

DNR ownership parcels within state

DNR administrative units within state

Corner data within the state

Partner data to be integrated for test county (if data is available):

U.S. Forest Service ALP data for test county

Bureau of Land Management (BLM) Geographic Coordinate Database (GCDB) for test county BLM ownership parcels for test county

Interagency Committee for Outdoor Rec. (IAC) updated state park ownership data for test county

Snohomish County administrative taxing districts, PLSS data, and government lot data

Longview Fibre Ownership

Federal Geographic Data Committee (FGDC) Logical Data Model Entity Use:

All entities from the FGDC data model will be used in the requirements logical modeling.

Initial data integration:

Initial data integration for the test county will be supported by the data providing organizations either through dollars, personnel time, or a combination thereof. Cadastral data transfer profile automation tool development will be tested in cooperation with the Bureau of Land Management and associated contractors.

Data maintenance:

The Department of Natural Resources data updates will be refreshed at least once per month to the Internet framework dataset. Partners that will be contributing data for the test county will provide updates based on data agreements to be drafted. Future phases may address cadastral data transfer profile updates or Internet transactional updates from partner organizations.

Data access:

The cadastral framework data will be available over the Internet to all framework partner organizations. The data will be made available in shape file format and possibly other formats if necessary and feasible. Framework partners will only need an Internet connection and a JAVA enabled browser for data access. Partner data downloading will be tested and evaluated for recommendations to future phases. Future phases may address a more open Internet access environment.


PHASE 1 - September 1, 1997 to August 31, 1998

Pilot County Criteria/Pilot County Selection

Pilot County Selection Criteria:

1. Test county has to have at least three willing data providers from at least two levels of organizations (federal, state, local, private, tribal).

2. Test county does not have overly complex cadastral data.

3. Partner data integration "exercises" the FGDC data model.

4. Test county partnerships must meet phase1 objectives and timelines.

5. Test county assessor data for exempt and taxable lands resides on a geographic information system (GIS) that meets phase 1 accuracy and scale requirements.

6. The test county assessors office must have an interest in participating in the project.

Pilot County Selection:

Snohomish County
